I began degreeing my cam today and ran into kind of a weird problem.
-I got #1 up to top dead center
-installed timing gears with marks on teeth FACING EACH OTHER crank sprocket on "0" degree keyway.
-While turning crank clockwise... as you approach TDC on #1, the intake valve begins to open!! At TDC #1 it's open .060"! I checked that with a dial indicator right on the lifter.
I compared the new cam gear with another one and the timing mark is in the right position. The dowl pin in the cam looks right too.
What do you think?!!
